Essential!
Works flawlessly with spectra. You’ll want spares of these so you don’t forget them at home!

Good replacement for spectra
I have bought a zillion of these to replace with my spectra and have a back up set if my parts aren’t clean and ready when I need to pump. They woork perfectly and fit well with the tubing and flange.

Great!
These were great replacement parts. Unfortunately, I dropped a flange and they were connected and it snapped. So they're not extremely sturdy, but they're well worth the price.

I've been using this product for a few weeks and ready to write a review. My pump is Ameda Maya- which is a great pump on a side note- and I ruined the plastic part of the backflow in the dishwasher. This replacement part is high quality and works fine with Ameda Maya, I know it's designed for Spectra, but also compatible with the Maya.

Happy for product, works well. Better than paying the full price on original website. Able to use it again with my second baby and still good condition!

I exclusively pump for my little boy and his Dad accidentally stood on the backflow protector for my Spectra S1 breaking it. I ordered this as a replacement, it was delivered extremely quickly and works perfectly meaning I could continue pumping for my son.
